       adt-virt-lxc - autopkgtest virtualisation server using LXC


       adt-virt-lxc [options] lxc-container


       adt-virt-lxc  provides  an  autopkgtest virtualisation server using LXC. It adapts the raw
       functionality provided by the lxc-* tools for use by autopkgtest.

       Normally adt-virt-lxc will be invoked by adt-run.

       You can conveniently create a suitable container using the adt-build-lxc(1) script.


       adt-virt-lxc assumes that you have already prepared a suitable Debian based LXC container.
       See lxc-create(1) for how to create containers.


       -e | --ephemeral
              This  option  makes  use  of  lxc-start-ephemeral  to  create  temporary  container
              overlays, instead of the default behaviour of cloning your containers. This can  be
              used  to  dramatically  improve performance, although you may see issues due to the
              overlayfs  filesystem  as  used  by  lxc-start-ephemeral   not   being   completely
              transparent  (e.  g.  seen  with  tar failing when running LXC within Qemu). Before
              using this option in automation you should ensure that tests that involve large I/O
              work as expected.

       -s | --sudo
              Run lxc-* commands through sudo; use this option if you run adt-run as normal user,
              but need to run the  container  itself  as  root  (if  you  use  LXC  system  level

              This  option is intended for test developer use. It enables the use of eatmydata(1)
              inside the container on all commands in order to improve performance. This requires
              eatmydata(1)  to  already be installed inside the supplied template, which you will
              need to do manually.

              However, since eatmydata is not part of the dep8 specification and may  affect  the
              test environment, it is not recommended for use in automation.

       -d | --debug
              Enables debugging output.


       The  behaviour  of  adt-virt-lxc  is  as  described by the AutomatedTesting virtualisation
       regime specification.


       adt-run does not run apt-get update at the start of a package build,  which  can  cause  a
       build  failure  if you are using a development release template. You will need to run apt-
       get update in the template yourself (e. g. using --setup-commands).


       Create a suitable debootstrap-based container for Debian or  Ubuntu  template,  e.   g.  a
       Debian sid one (will be named adt-sid):

              adt-build-lxc debian sid

       Or  an Ubuntu one based on the cloud images (faster than adt-build-lxc's "ubuntu" template
       with debootstrap, but much bigger):

              lxc-create -t ubuntu-cloud -n adt-trusty -- -r trusty -d daily

       Run tests against hello_2.8-4.dsc, using the LXC container adt-sid, and with an  ephemeral
       overlay for speed:

              adt-run hello_2.8-4.dsc --- adt-virt-lxc -e adt-sid


       adt-run(1), adt-build-lxc(1), lxc-create(1), eatmydata(1), /usr/share/doc/autopkgtest/.
